Yep, well said, Foolestroupe. I wasn't having a dig, it's just that I had that sodding moth coming out of my ears for twelve years on the exam board!

Actually, they're very pretty. We had one on an apple tree trunk last week and my wife had to look twice to see it at all. As we're in unpolluted Kernow, you won't be surprised to hear it was a light one! They're also incredibly well camouflaged on natural concrete paving slabs.
